[PATCH] genirq: Refactor actions_show loop block using a common macro to go through the actions list

[Paran Lee]

Hello, I am Paran Lee.

Since we have a macro defined in our IRQ subsystem internal functions to
traverse the list of actions, how about refactoring this loop?

- genirq: Use a common macro to go through the actions list
(f944b5a7aff05a244a6c8cac297819af09a199e4)

have a good day!
Paran Lee.
